Correct Answer: C
Solution :
Magnetic moment is from 5 to N \[{{m}_{net}}=\sqrt{{{m}^{2}}+{{m}^{2}}+2{{m}^{2}}\cos \theta }\] \[{{m}_{net}}\] will be maximum if cos6 is maximum. \[\cos \theta \] will be maximum when q will be minimum. So, at \[\theta ={{30}^{\text{o}}}\,{{m}_{net}}\] will be maximum.
